Kate Middleton: The Duchess Of Photo Calls?

Whether it's getting stuck in planting a tree or ironing with Prince Charles, the Duchess of Cambridge is the princess of photo calls.

During a visit to the East Anglia's Children's Hospices on Monday Kate was happy to pose while planting a tree - in some rather impractical high heels.

As her profile has risen following her marriage to Prince William, we've seen Kate playing hockey, speaking in public, and drinking a smoothie named 'the Duchess.'

The Duchess even got involved in a ceramic class with husband William during their recent visit to Canada - and sported a fetching cowboy hat.

To celebrate her first public speech on Monday here's a gallery of Kate's greatest photo-ops.
